Most, if not all, of the samsung small electronics (phone, tablet, ECT.). I don't think it will work for Samsung Tvs, blenders, laptops (unless you need a cord to plug in a Samsung phone or tablet to the laptop, then it works fine), vacumcleaners, or the like. If you are concerned about which power cable to use for which electronic I would recommend A) labeling the cords that came with your electronic originally with clear bold labeling, or B) bringing in/ knowing the make and model to be able to ask someone at the geeksquad counter.

Good luck! I hope this helped.
